The description of area-area spatial relations are enhanced by these metric parameters, and the parameters are widespread applied on spatial query and spatial analysis.
这些度量参数加强了面对象间空间关系的描述，可广泛应用于空间查询和空间分析中。
If a project is moving outside those parameters, or is about to, you want the metric at hand to indicate such deviation.
如果项目偏离了那些参数，或将要，您想要让手边的度量标准指出这样的偏离。
By using the similarity metric, valves can be classified into groups. Contrasted parameters between products group and new product needs, information of similarity product will be found out.
通过对产品间相似性参数的研究可以将阀门产品分为若干产品组，通过对新产品设计任务的参数值与各组产品参数值的对比，就可以迅速得到相似产品的信息。
